The Roberts House is a historic building in Canonsburg, Pennsylvania, listed on the National Register of Historic Places. It is designated as a historic residential landmark/farmstead by the Washington County History & Landmarks Foundation. The Greater Canonsburg Heritage Society erected a historical marker near the house, which is the last remaining structure from Jefferson College. The history of the building can be traced back to the founder of Canonsburg, Colonel John Canon, and Reverend John McMillan, the founder of Jefferson College. Over the 200 years since it was built, the building was sold numerous times, including to the adjacent Jefferson College or someone connected to the college. A joint effort between the Washington County Cultural Trust and the Pittsburgh History and Landmarks Foundation was developed in 2006.

By 1798, John Watson, the Jefferson College professor who would become the first college president, was residing there. The property was then purchased by its namesake John Roberts in 1803. He operated a store there. A series of quick sales ensued: the property was sold to Abraham Lattimore 1815, then to Washington lawyer Joseph Pentecost in 1817, then to David Hoge in 1819, and to Alexander Short in 1829. Short operated a store in the home, but lost the property in a sheriff's sale in 1832, where it ended up in the hands of John K. Wilson. In 1840, Wilson exchanged the property with President of Jefferson College Matthew Brown for 5 lots in Washington plus a token $1. Brown immediately deeded the property to Jefferson College.
